NE-033: A grab sample station from the sewage Ueatmcut plant intake and discharge. <br />• Because the mine was inactive throughout the year, the sewage treatment plant was not <br />operated and no discharge occurred. <br />Alluvial Wells <br />Location, surface elevation, total depth, zone uC completion, and muuitoring purpose are <br />provided for all wells iu Table 1.2-3. <br />PAW-1: A dip sample from an alluvial well located to the south of the I'urgatoi~e <br />River in alluvium adjacent to PRS-I. This sample station was established to monitor water <br />quality above significant mining activity. Data collected at this station (annual miniuuun, <br />maximum, mean) from 1984 to date are presented in "fable I3-I . <br />PAW-2: A dip sample from an alluvial well located to the north of and adjacent to the <br />Purgatoire River approximately 200 yards downstream of I'AW-I. 'this sample station <br />was established to monitor water quality down gradient from the underground coal <br />development refuse pile at the New Elk Mine. Data collected at this station (annual <br />minimum, maximum, mean) Gom 1984 to date arc presented in 'fable 13-2. <br />PAW-3: A dip sample from an alluvial well located to the north ufuul adjacent to the <br />Purgatoire River approximately 300 yards downstream of PAW-2. During March and <br />April of 1985, 500 feet of the Middle pork of the Purgatoire River was diverted to the <br />north to create additional room for the coal stockpile at the New Llk Preparation Plant. <br />The diversion was cut through an existing refuse disposal area. PAW-3 was established to <br />monitor the quality and quantity of water movement into the upstream (west) end of the <br />backfilled chamtel. Monitoring of this station was eliminated in 1999 with elimination of <br />the diversion survey. <br />PAW-4: A dip sample from an alluvial well located to the north of and adjacent to the <br />Purgatoire River approximately 100 yards downstream of PAW-3. The well was <br />established in the backfilled channel during the diversion of the Purgatoire River. It was <br />established to monitor the quality and quantity of water movement into the downsu~eam <br />(east) end of the diversion. Monitoring of this station was eliminated in 1999 with <br />elimination of the diversion swvey. <br />t3 <br />
